Thanks for being so open...first thing that seems important for me to say is that you don't need to be fixed....possibly embracing your gentle nature and not beating yourself up for how you are in the world. This dating thing and online world to do so can be very scary and intimidating so just know you are not alone in that and many people with whom you interact might be going through all that you are. The key to negotiating this is to have an open mind about it all and know that not everyone will be for you...you worry about the rejection piece, which of course is normal, but let's not forget you might not be interested in everyone either. Try to message a few women, take your time, don't reveal everything all at once and schedule some coffee time, drink time or dinner time. Prepare to feel uneasy about it....it's new to you and that is okay. In terms of this woman, I would reach out again maybe tomorrow and let her know you are still interested in meeting this week and hope she feels the same and to let you know either way. A thick skin while doing this dating thing is needed...doesn't mean to harden yourself to the experience, only to know that there may be some good experiences and some less good....but what's the alternative? It can be to be on your own and if that is your choice, that is fine too, but I am not hearing that, so it may take you some practice and patience and feeling uneasy, but you can get through it. Like anything new, it can take some time to adjust...give yourself that time and flexibility.
